Sikhism is a 500-year-old monotheistic religion founded by Guru Nanak in 1469 in northwest India, emphasizing equality among all people and devotion to one God. The faith evolved through ten successive gurus, promoting community service, social justice, and the rejection of caste distinction, while key symbols include the five K's and the Guru Granth Sahib as a living guru. Central practices involve congregational worship, the Gurdwara, and emphasis on personal conduct aligned with Sikh teachings and values.
